On Quantum Obfuscation

Understand

Encryption of data is fundamental to secure communication in the modern world.

• Beyond encryption of data lies obfuscation, i.e., encryption of functionality.
• It is well-known that the most powerful means of obfuscating classical programs, so-called ``black-box obfuscation',' is provably impossible [Barak et al '12].
• However, several recent results have yielded candidate schemes that satisfy a definition weaker than black-box, and yet still have numerous applications.
